| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1.a requires, in part, that written procedures shall be established, implemented and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Revision 2, Appendix A, Section 9.a, requires, in part, that maintenance should be properly pre-planned and performed in accordance with documented instructions appropriate to the circumstances. Contrary to the above, on October 19, 2016, the licensee failed to properly pre-plan and perform a post-maintenance test in accordance with documented instructions appropriate to the circumstances. Specifically, the post-maintenance test for work performed on valve EFHV0066, the essential service water to ultimate heat sink cooling tower train B bypass valve, did not include a seat leak test, which would be necessary for the work performed. As a result, on November 17, 2016, operators discovered this valve leaking by at approximately 3900 gallons per minute. The licensee subsequently determined that the safety function of the ultimate heat sink would not be adversely affected with leakage up to 4100 gallons per minute. The inspectors evaluated the significance of the issue under the Significance Determination Process, as defined in Inspection Manual Chapter 0609.04, Initial Characterization of Findings, and 0609 Appendix A, The Significance Determination Process (SDP) for Findings at-Power, dated June 19, 2012. The inspectors concluded the finding was of very low safety significance (Green) because all questions in Exhibit 2 could be answered no. The licensee entered this issue into their corrective action program as Condition Report 201608791. |
